With a triple-edge design, the head reaches everywhere without missing spots.

A two-tank cleaning system separates clean and waste water, ensuring the roller is always clean. Both have similar self-cleaning technology.

Top-tier Steam cleaners

The main difference:

The Steam modification works as a wet cleaner using high-pressure/high-temperature steam to tackle stains.

The Master series mops the floors with heated water and tackles stains by using a blast (high-pressure solution spraying).


The Master

The Tineco FLOOR ONE S9 Master has two big upgrades:

  1. ThermoBlast technology
  2. Continuous hot water mop

What is ThermoBlast?

High-pressure hot water blasts away stubborn stains like grease, dried-on debris, and dirt from crevices, etc. Helps to blast debris from crevices and remove sticky stains.

Performance:

  • Blasts hot water at high pressure to remove stains
  • Mops with hot water, continuously keeping a high temperature 
  • Green headlights light up the dust
  • iLOOP adjusts cleaning settings for messy areas
  • Self-cleans with hot water and heated air
  • Has a StreakFree scrapper to remove water stains.

Another BIG feature is the hot mopping.

126°F Continuous Hot Water Mopping heats water for the best mopping results

As a mop, the S9 Master is the best of the series.

Steam

The Steam modifications don't need liquid for tackling stubborn stains.

It also features a better appearance and upgraded cleaning systems, including a self-cleaning mode.

FlashDry Self-cleaning System: 2min self-cleaning & 5min flash drying with 185℉ air.

The longest battery life on the market

The quick charging has been seen in the latest S9 Artist series only.


Summing up

Both are similar in performance, only different in the ways of reaching the results.

While the FLOOR ONE S7 Stretch Steam is a steam cleaner that deals with dry stains and sterilizes the floors with steam, the Floor ONE S9 Master heats water for mopping and blasts the solution for better results.
